Agreed that this would be a useful feature. It would require a slightly deeper drive into the fortran code. driver.f90
just passes the same diagnostics reported by the original RRTMG_SW code through to the Python wrapper.
Thanks!
I'm looking in the rrtmg_sw_rad.f90 script — it looks like these are the optional output variables that we want.
So, i think the steps would be 1) change the intent of this variable to "out" in the rrtmg_sw_rad.f90 script, and 2) add this variable to the output from driver.f90 here https://github.com/climlab/climlab-rrtmg/blob/3db6e66b1c735c694ca2f37fd259d73bb26868e9/climlab_rrtmg/rrtmg_sw/Driver.f90#L237
And also add the new variables to the f2py declarations here: https://github.com/climlab/climlab-rrtmg/blob/3db6e66b1c735c694ca2f37fd259d73bb26868e9/climlab_rrtmg/rrtmg_sw/Driver.f90#L245
Does that sound about right? Any pointers are appreciated.
That sounds more or less right, except that there would need to be a new switch to turn on the optional extra output. The Python wrapper that calls this module would default to setting this switch off, to preserve backwards compatibility.
There is some work happening concurrently in a different project that is looking at enabling full spectral output from RRTMG. I think it will be worth taking the time to think through what a consistent interface should look like for turning on and off various optional output.
If you're interested in roughing out a PR that handles diffuse / direct part, I think that would help nudge these efforts along @bsu-wrudisill!
Hello,
Here is a feature request. I would like to be able to output the direct and diffuse components of downwelling shortwave radiation. It appears that this might be straightforward to do.
I think that by modifying the driver.f90 script might be possible.
